The SOLEIL synchrotron
In a facility such as SOLEIL, electrons of very high energy (their nominal energy is of 2750 MeV) rotate at nearly the speed of light in a 354 m circumference storage ring. The emission of radiation is tangent to the trajectory in an extremely thin “light” line, when the electrons trajectory is curved with a magnetic field that plays the role of the nuclei electric field. The synchrotron radiation, produced in bending magnets and Wigglers inverters used for insertions), is filtered in energy or wavelength and directed by optical systems in beamlines towars experimental stations.
